Saaweeeet!

Just did my first bucket-less 50G water change using nothing but my iPhone Apex App and 3 ball valves. It was magical!

Open a ball valve and my closed loop pump sends 50G to the drain, close the drain and shut down my closed loop pump, open up the ball valve coming from a Mag 12 in my mixing barrell and turn that pump on and it pumps 50G back in. All in under 10 minutes!

In 12 hours I can add salt to the new 50G of RO/DI water and I'm ready for another.

BTW, my mixing station is 40 feet away from my DT in my furnace room.
